A student redid the experiment of mixing room temperature water and warm
water. This time, she used half the original amount of warm water. How will
the final temperature be different?
A. It will be lower, because the amount of water in the mixture will be
less.
B. It will be higher, because all parts of the mixture will end up at the
same temperature.
C. It will be the same, because all parts of the mixture will end up at
the same temperature.
D. It will be lower, because less thermal energy is transferred to the
room-temperature water.
